yes m8 change my final drive from 3.82 to either 3.58 or 3.33, bigger exhaust housing from 0.64 to 0.86 and maybe look at a wilder cam profile.
also set my boost control so i can have different boost pressures per gear at the moment its all or nothing and i have done faster 1/4 times with less power.
after christmas i need to purchase a set of toyo r888 there such a bid difference in grip compared to normal road tyres.
